* Set more precise React/React-Native package version dependencies
- In general, try to avoid breaking changes caused by >=
- In particular, such a breaking change can be seen by testing the current Example
app on Android with the existing package.json's and RN 0.43+, which causes errors
in MainApplication public/protected method settings.
* Revert changes to main package.json
- Would erroneously break compatibility for main package
- Leave precise dependencies only for Example app, since this does not impact
compatibility in the same way
* Android tap-to-focus and improved (continuous) auto-focus
Tap-to-focus
- On tap, compute focus area around motion event's location, and pass this to the camera parameters
as the new focus area.
- Adds RCTCameraUtils.java file, so far with only a single function that helps compute the focus area
from a motion event. This file can serve as a location for utility constants and functions for the
rest of the app, where such things can be extracted out.
Improved (continuous) auto-focus
- Use FOCUS_MODE_CONTINUOUS_PICTURE/VIDEO when possible to enable continuous auto-focus; fall back to
FOCUS_MODE_AUTO otherwise, if able.
Other changes
- Update README to specify differences between iOS and Android for focus and zoom functionality.
- Update AndroidManifest with more thorough list of permissions and features.
- Update Example package.json react and react-native dependencies to match root package's package.json.
* Example: default empty onFocusChanged callback
- Enables default tap-to-focus behavior in Example app, facilitating
testing of focus features in the Example app
* iOS: minor focus and zoom changes
RCTCameraManager focusAtThePoint improvements
- Dynamicaly get size from bounds of camera view, instead of full screen, since
it might not always be the case that the Camera react component is taking up
the entire device screen.
- Also add setting exposure to the same point of interest we are focusing on.
Example
- Add onFocusChanged and onZoomChanged empty callback functions by default to
Example app, allowing tap-to-focus and pinch-to-zoom to be readily
experienced/experimented with.
- Updated react/react-native dependencies to match root package.json.
TODO/Other remarks
- Tap-to-focus seems to still not work perfectly... From logging, it always seems
to get the right location in the view (meaning its getting the right location
from the user touch and transforming it to the {0, 1} range appropriately), and
does indeed engage the focus process, but it seems it sometimes refocuses on the
center-ish region of what's in the camera instead of the location that was actually
pressed. I thought this might be related to the subjectAreaDidChange getting called,
which in turn sets the focus mode to continuous auto-focus at the view center, but
from my experimenting, this method never actually gets called. I wasn't able to
figure out if there's somewhere else in the library that's forcing continuous auto-focus,
or if there's just some bug in our current focus procedure within focusAtThePoint.
* Reset Example/package.json dependency versions to master
* Update compileSdkVersion to 25 and buildToolsVersion to 25.0.2
Best to keep these up-to-date. Doesn't affect backwards compatibility.
* Add buildToolsVersion requirement of 25.0.2.
* * removed some of the re-parsing of the output image byte array
* removed re-saving of output file
* moved image processing onto an async task to allow camera to be used while processing is running
* added jpeg compression support for android
* move explanation to correct bit of docs
* writing metadata.location (lat and lon coords only) to the exif data... and returning the internal url for the new image (which can be used in conjunction with the RN CameraRoll)
* just a tidy up to remove some duplication and fix some logging (no functional changes)
* oops, fix typo
* docs
* added mediaUri to ios so its the same as android
